Cancellation rate is cancellations divided by flights scheduled. On-time rate is on-time departures divided by flights flown, because a flight that was cancelled cannot also have left late. Each direction is counted separately: Sydney to Melbourne and Melbourne to Sydney are different flights with different records.
Which airline is most reliable on Brisbane to Sydney
Virgin Australia cancelled 1.4% of its flights on this route and Jetstar 4.4%. Same airports, same weather, same twelve months, so the difference is the airline: schedule, aircraft type and how much slack it leaves in the day.
| Airline | Cancelled | On time | Flights |
|---|---|---|---|
| Qantas | 2.3% | 82.9% | 6,199 |
| Virgin Australia | 1.4% | 78.7% | 5,490 |
| Jetstar | 4.4% | 64% | 2,658 |
An airline needs 200 scheduled flights a year on the route to appear here. Codeshare flights are reported by the airline that operates them, so a Qantas-numbered flight flown by QantasLink counts as QantasLink.

The flight home
The return leg is a different flight with a different record: Sydney to Brisbane is cancelled 2.3% of the time, less often than the outbound. Morning departures generally do better than evening ones on any route, because a delay early in the day follows the aircraft around for the rest of it.
If it is cancelled
About 341 Brisbane to Sydney flights were cancelled over the last twelve months, so on this route it is worth knowing the answer before you are standing at the desk. Australia has no fixed compensation payment like the European one. If the airline caused it you can ask for a refund or a seat on the next flight, on any carrier, and most airlines will cover a meal and a hotel. If it was weather or air traffic control, you get the later flight or your money back and nothing else.
Booking Brisbane to Sydney
You know the route's record now. This searches fares from Australia, on every airline flying them.
Fares are searched live and are not ours to quote, so these go straight to the search rather than showing a price that would be out of date by the time you read it. We earn a commission if you book, at no extra cost to you, and it does not change the figures above.
Flying domestically? The rules are not the international ones
There is no 100ml liquid limit on an Australian domestic flight, and no need to take your laptop out. There is a quarantine rule on fruit and vegetables between states that catches people constantly.
